Helios Fans HQD 710/6

The Helios HQD 710/6 is a medium-pressure axial fan engineered for industrial ventilation and HVAC applications where quiet operation and energy efficiency are essential. It features a robust 710mm galvanized steel cylindrical casing with standard flanges (DIN 24155 Part 3), ensuring easy integration into duct systems.

This fan is powered by a 3‑phase, 6‑pole direct-drive motor, which operates at a lower rotational speed than 2- or 4‑pole motors. This makes it ideal for applications requiring low noise levels without compromising airflow performance — perfect for sound-sensitive environments such as warehouses, production facilities, and large commercial spaces.

The HQD 710/6 uses a dynamically balanced impeller that is optimized for aerodynamic performance and complies with DIN ISO 1940 – 1 (class 6.3), ensuring low vibration and long service life. It comes with sealed-for-life ball bearings, integrated thermal protection, and an IP54-rated housing for reliable operation in demanding conditions.

This model supports speed control via voltage reduction, allowing precise performance tuning for specific ventilation needs. With suitability for air temperatures up to 60°C, the Helios HQD 710/6 offers a versatile, durable, and quiet ventilation solution for industrial and commercial environments.
